It accelerates laterally. The brake though, decelerates (-ve acceleration) but only until v=zero after which it doesn't decelerate any more.
No, the steering wheel does not accelerate laterally. It just changes the direction of the front wheels which dictate the direction in which a vehicle is accelerated.
RCS thrusters for example are accelerators. A steering wheel is not.
Would the steering wheel have the accelerating wheel on the side of the car it is supposed to turn slow down (like how track tanks turn) it would be an accelerator.
Acceleration and velocity are both vectors dude, they have magnitude and direction. Acceleration is a change in velocity over time, so if you're moving and you change directions, that constitutes a change in velocity, i.e. an acceleration.
Hell, Newton's second law: F=ma. Your car isn't going to change mass appreciably mid-corner, so we can say that the force you feel is proportional to your acceleration. Did you feel yourself turning? Felt your ass slide and body lean? You feel you experience a force, an acceleration.
This concept is foundational to elementary mechanics, you cannot pass physics 1, calculus 1, or I think even college algebra without knowing these concepts.
When you turn the wheel, do you feel a g-force to the side? If yes, you’re accelerating.
Changing direction is not acceleration. You also experience inertia when changing directions.
Your lateral velocity is changing. Change in velocity = acceleration. In fact, you’re now traveling in a circle, which requires constant acceleration towards the center.
Lemme break it down for ya:
Changing direction by definition is an acceleration. If it wasn't, then all our math about planets, rockets getting to planets, etc, would be wrong.
A steering wheel could be called a "centripetal accelerator", since it induces acceleration toward the center of a radius/circle.
This is high school level physics, one of the first things you learn.

Face it, planets are hanging from the celestial ceiling - on wires. Galilei's herecy has been debunked. The end is nigh! Eat more sawdust! Ahoohaa!
Yeah I think the guy above you has an argument though. The steering wheel only acts as an accelerator if the vehicle is actually in motion. But then the brake also does that, so maybe there is a point in naming them differently.
You need to revisit the concept of centripetal acceleration. You are remembering incorrectly. Any change in the velocity vector is acceleration. That can be magnitude and/or direction.
